Abstract

The invention discloses a mold for a head, neck, chest and abdomen tumor radiotherapy simulation and detection structure. The mold mainly comprises a moving platform support, am moving platform, a control box and a human body surface simulation rack, wherein the moving platform support comprises a positioning plate, a fixing button, a bracket, a supporting platform and an adjusting support; the moving platform comprises a sliding platform, a sliding platform support, a rotating support, a simulation tumor object, a lead screw, a stepping motor and a limiter; the human body surface simulation rack comprises a body part and a head and neck part. The mold for the head, neck, chest and abdomen tumor radiotherapy simulation and detection structure has a simple and reasonable structure, and can be used for analyzing and researching setup errors of head, neck, chest and abdomen tumors in the field of clinical tumor accurate radiotherapy research and performing quality control and the like to the radiation field control performance and the like of a multi-leaf collimator of radiotherapy equipment.

Description

technical field [0001] The invention relates to a medical device, in particular to a mold of a radiotherapy simulation and detection structure for head, neck, chest and abdomen tumors. Background technique [0002] With the development of precise radiotherapy technology, the role of radiotherapy in the comprehensive treatment of tumors is gradually increasing. Precise radiation therapy is the development goal of radiation therapy, which requires precise positioning of tumors, precise design and precise execution of treatment plans. Its application can reduce the probability of complications in normal tissues around the target area, increase the irradiation dose in the tumor area, and increase the tumor control rate. However, the more precise the radiotherapy, the higher the accuracy of the irradiation position and irradiation field. Due to factors such as equipment uncertainties, technician's positioning technique, patient position movement, and inaccurate body surface lan...
